Abstract

A golf club head comprises a body having a face, a crown and a sole together defining an interior cavity. The body having a channel located on the sole and extending generally from a heel end of the body to a toe end of the body. A weight member movably positioned within the channel such that a position of the weight member within the channel is able to be adjusted, thereby adjusting a location of a center of gravity of the body. Additionally, adjustment of the weight member provides a maximum x-axis adjustment range of the position of the center of gravity (Max ΔCGx) that is greater than 2 mm and a maximum z-axis adjustment range of the center of gravity (Max ΔCGz) that is less than 2 mm.

the golf club head further comprises an adjustable head-shaft connection assembly comprising a sleeve secured in place by a fastening member in a locked position, wherein the adjustable head-shaft connection assembly is configured to allow the golf club head to be adjustably attachable to a golf club shaft in a plurality of different positions resulting in different combinations of loft angle, face angle, or lie angle;

the golf club head further comprises a plurality of ribs located on an internal surface of the sole portion;

the golf club head further comprises one or more weight ports and at least one weight removably attached to the one or more weight ports;

the one or more weight ports comprise a first weight port and a second weight port;
